Abstract
Simple hydroxamic acids (XHAs) are salt free, organic compounds with affinities for cations such as Np4+, Pu4+ and Fe3+. As such they have been identified as suitable reagents for the separation of either Pu and/or Np from U in modified or single cycle Purex based solvent extraction processes designed to meet the emerging requirements of Advanced Fuel Cycles. Acid catalyzed hydrolysis of free XHAs is well known and may impact negatively on reprocessing applications. The hydrolysis of metal-bound XHAs within metal ion-XHA complexes is less understood.Using a model derived for the study of hydroxamic acid hydrolysis in the presence of non-oxidising metal ions (Np (IV) and Fe(III)), we review data pertaining to the hydrolysis of hydroxamic acids in the presence of the oxidising Pu4+ ion, under conditions where the influence of the redox processes may potentially be neglected.
